Hi guys, I have a question that I'm not getting much help with. Does john deere service advisor software work on reading the older 220-3 hitatchi units? I do have service advisor software and I know I would require the w9 cable to go from laptop to excavator but it's fairly expensive. Just curious if anyone has done this before. I have read that dr ex and windr will read john deere but have not seen anything on it going the other way. Thanks
